EDWIN F. GUTH, OF ST. LOUIS, MISSOURI,

LIGHTING-FIXTURE.

Application filed August 18, 1915.

To all whom it may concern:

Be it known that I, EDWIN F. GU'rH, a

citizen of the United States of America, residing at the city of St.Louis, State of Missouri, have invented a certain new and usefulLighting-Fixture, of which the following is such a full, clear, andexact description as will enable any one skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to a lighting fixture, and its object is to producea form of construction which will embody a minimum number of parts, andone which may be easily wired and assembled. In my improved constructionthe supply wires may be attached to the contact terminals before thefixture is assembled, or any part thereof is attached to the wall orceiling, the terminals being carried on a separable part which may beeasily placed and secured in position.

In the drawing, which is a sectional view illustrating my improvedfixture, 1 represents the canopy, which is constructed of insulatingmaterial, such as vitreous china. This canopy bears against the wall orceiling line 2 and is supported from the junction box 3 either by meansof a strap 4 supported from the central stud 5 of the junction box, orby ears 6 of the junction box when these are provided. Screws 7 passthrough the canopy and their threads engage with the threads in thestrap 4., or with the threads in cars of the junction box, in which casethe strap 4 may be omitted.

The canopy is provided with a threaded central opening into which a lampreceiving shell 8 may be screwed, this shell being provided withexterior as well as interior threads. The shell 8 is supported on theinsulating base 9, which carries the contact terminals to which thesupply wires 10 are attached A rubber Washer 11 may or may not beinserted between the base 9 and the canopy 1. In order to prevent theshell 8 from turning and therefore retreating out Specification ofLetters Patent.

of the opening in the canopy when the lamp is inserted, I preferablymake the lower portion of the opening of the canopy wider than theremainder and thereby provide a shoulder 12. After the shell 8 isinserted its edge may be bent to engage this shoulder and thus preventturning.

It will be noted that this fixture is of very simple construction; thatthe wires may be attached to the contact terminals on the base 9 andthen the base placed in position in the canopy by screwing the canopy011 the shell 8. Thus the whole fixture is wired and assembled prior toattaching it to the ceiling or other support.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. In a lighting fixture, the combination of a canopy provided with athreaded Opening, a socket member comprising a base of insulatingmaterial and an exteriorly and interiorly threaded lamp receiving shellpermanently attached to the base and adapted to be screwed into thethreaded opening in the canopy from the inside, and means for preventingthe shell from turning when a lamp is inserted.

2. In a lighting fixture, the combination of a canopy provided with athreaded opening, and a socket member comprising a base of insulatingmaterial and an exteriorly and interiorly threaded lamp receiving shellper iuanently attached to the base and adapted to be screwed into thethreaded opening in the canopy from the inside, a portion of the loweredge of the shell being bendable outwardly to engage the canopy andprevent the shell from turning when a lamp is in serted.

In tesb'mony whereof, I have hereunto set my hand and affixed my seal inthe presence of the two subscribing witnesses.
